TXLUGNUT (aka my boyfriend) changed out the oil in the transmission (I think it was the transmission) along with an animal nest of some sort that has been in it a long time, and the Clutch spring came off too. We can't figure out how it goes back on and he said we may have to remove the gas tank and a couple of other compenets to get it back on. Any ideas on how to get it back on without tearing the tractor apart? It's a 1953 Farmall Super C. Thank you in advance!
